Sulfur Recovery Daily Question 2019.1.1

The liquid sulfur pipeline of the unit, running from the sulfur condenser to the liquid sulfur tank, is unobstructed; as a result, the toxic and harmful gases containing HS and SO present in the sulfur condenser are carried away along with the liquid sulfur through this pipeline. The function of the sulfur seal tank is to contain these gases using the static pressure of the liquid sulfur. The sulfur seal depth in this unit is 3.4 meters, while the pressure required to break through this seal is 50 Kpa.

The first step is to achieve gas-liquid separation, that is, the separation of sulfur from the process gas; the sulfur flows into the sulfur seal and then from there to the sulfur storage tank or pool. The second sealing function is to isolate the process gas within the process gas pipelines, preventing it from leaking into sulfur tanks or the atmosphere. The temperature of the process gas is also high, and it consists of toxic and harmful gases that cannot be released into the atmosphere casually. The third protective function is that if there is a blockage in a subsequent section or if the pressure of the purge gas suddenly increases due to certain raw material gases, the pressure at the fan outlet rises. If this pressure increase is too rapid, it can damage the fan, the instruments, and the structure of the catalytic bed. However, before such damage occurs, the sulfur seal’s breakdown pressure is reached first; the sulfur contained within the sulfur seal is blown out, allowing the process gas to communicate with the sulfur tank or the atmosphere, thereby enabling pressure relief. Fourth, for sampling purposes: if you are using observation holes in the sulfur sealing strips, during shift changes and routine inspections, it is necessary to monitor the sulfur flow rate and quality, as well as take samples for testing, so that adjustments can be made promptly. It is also necessary to ensure proper insulation; if the insulation is inadequate, sulfur caking occurs, which is very troublesome and difficult to clean up and resolve. At the start of operation, sulfur should be injected into the device in advance; the liquid level should be at the lower edge of the sulfur outlet. The valve on the sulfur feed pipe should be closed to prevent impurities from entering during the soot-blowing and heating processes. Once the desired temperature is reached, the vent valves at the front and rear of the device should be closed. After soot-blowing is complete, acid gas can be introduced before the valve on the sulfur feed pipe is opened.
